stat_summary：使用单独的数据帧的boxplot的posthoc标签

Question

我尝试使用以下代码在每个箱图上创建一个带有矢量（stat_summary）的posthoc标签的箱线图。

向量按照我希望我的标签在箱图中显示的方式排序，但CLD.gm2.lf.group [1] " a" " a" " a" " a " " ab" " b" " ab" " b" " a " " a" " a" " a" " a" " a" [15] " a" " a" " a" " a" " a" " a" " a" 似乎混淆了图上标签的顺序。

例如，我的矢量，按照我想要的方式排序：

ggplot(Total.Grad, aes(x, y, fill = treatment)) +
 geom_boxplot(aes(fill = treatment)) +
 theme_light() +
 ylim(5,28) +
 scale_fill_brewer(palette = "YlGnBu") +
 stat_summary(geom = 'text',
              size = 3,
              label = CLD.gm2.lf.group,
              fun.y = max,
              vjust = -1,
              position = position_dodge(width = 0.9))

以下代码的箱形图：

<VirtualHost *:443>

    ServerName myapp.org

    ProxyRequests Off
    ProxyPreserveHost On

    # proxy pass /myapp to the internal:6543/myapp
    ProxyPass           /myapp       http://172.31.15.111:6543/myapp/
    ProxyPassReverse    /myapp       http://172.31.15.111:6543/myapp/

    <Proxy *>
        allow from all
    </Proxy>
    ProxyTimeout 1200


</VirtualHost>

正如您所看到的，它始终翻转“最小”。和＃＆＃39;广泛的＆＃39;。它不是按字母顺序排列的。为什么它会以一种特定的方式混淆一个向量，而不是经常在整个情节中粘贴它？
